This is a useful feature for anyone who takes notes on their phone, or who has video as part of their demonstration. The RoyalTek RPJ-2000 also supports netbook and notebook laptops via VGA, and will also support PDF and MS office files, a must for the business setting. The maximal screen projection size it 65", which is usually big enough to for a room full of people. This projector only needs 3 seconds to turn on. This is a handy feature for anyone worried about forgetting to boot up before the big presentation. The RoyalTek RPJ-2000 is purported to be the first "full-featured" Pico-Projector, and the price does not seem unreasonable, but there have not been many reviews of this product.
